one more thing. i had no problem with my strut tower brace(cusco) i just had to bend the ac lines a little...
I was told by people who should know that if you bend the AC lines (which are aluminum) to fit a large intercooler this will cause an imperceptible crack in the tubing (steel bends, aluminum cracks) and eventually all of the freon WILL leak out. You need to get the STi AC lines which are actually bent from the factory to accommodate the larger intercooler and lie closer to the firewall. They probably cost around $80 and of course you will have to re-charge your AC system with new freon witch will cost another $100. So for a larger TMIC you should expect to spend an additional 180-200 bucks.
I am not speaking from personal knowledge but fron the words of several folks who are in the business of Subaru aftermarket parts and installations.
